Seagate Technology has just released information to DailyTech with regard to the company's upcoming highest capacity hard disk drive to date. At 1TB, if no other hard disk drive manufacturer can catch up, Seagate will have the highest capacity hard drive product to market first.

The 1TB hard disk drive will be based on perpendicular recording technology which packs bits tighter onto the magnetic platter by positioning them perpendicular to the platter as opposed to linear recording which positions bits horizontally. The perpendicular recording technology, which has been in use by Seagate and its platter supplier for over a year now, will be put to the test as Seagate states the 1TB product will implement fewer platters and heads to improve the performance of the drive.

In a statement to DailyTech earlier today, the company claimed:

Seagate’s 1TB hard drive will be our second generation 3.5-inch hard drive to
feature capacity-boosting perpendicular recording technology, and it will use
fewer heads and discs than similar-capacity products we expect to see from our
competitors. It is clear that fewer heads and discs, along with our proven
perpendicular technology, can increase drive reliability, and also reduce
operating temperatures, power consumption, noise, and weight.

It is confirmed now that we should expect a 1TB Barracuda from Seagate Technology to hit the market in full force sometime in the first half of this calendar year. Seagate was also the first company to announce a 750GB hard drive last year. No company has since announced a drive with 750GB or greater capacity.

Wrong, if they need to use powers of two, they shouldn't have used a prefix DEFINED as 1000. If you need to represent the numer 1024, do not take a prefix DEFINED to 1000. You have the KiB-prefix for 1024. The harddisk-makers follow the correct definition used for over a hundred years, and in any other field (and substainsial part of the computer-field also).

If this is your rationalization, then you just destroyed the entire concept of the metric system. Based on this, terms such as "kilometer" are invalid, because a meter isn't a number, it's a predefined length.

Where you're wrong is, kilometer (for example) only means thousands of meters, or when used with a number (i.e. 8 kilometers), it translates to 8 thousand meters. It's a system of abbreviation not translation! If a hard drive was 8 KB, 8 kilobytes means just what it says, 8 thousand bytes. Hence why your hard drive ends up being less than you expect, because the notation is not the same.

Kilo means 1000, it is defined as 1000, it makes perfect sense to say 1000 bytes. And if you need a prefix that means 1024, use another prefix than the one already defined as 1000, and used as 1000 in every imaginable field for hundreds of years.

Take it back to basics? 1GiB or 1 gibibyte is 1,073,741,824 bytes(i think), but 1GB is 1,000,000,000 bytes ,so when you buy an 80GB hard drive your a buying a 80GiB hard drive, which actually only has 74.5GB or gigabytes. its the manufacturer specifieing the wrong unit, although its just been accepted. so it you wanted to buy an actual 80GB hard drive it would be specified as 85.8GB by todays incorrect labelling, or 85.8GiB with the correct labelling.

When you buy a 80 GB disk you get 80 000 000 000 bytes. I other words you get 80 GB, Which is the same as 74.5 GiB. To get a 80 GiB HD, you must buy one labled as 80 GiB, or 85.8 GB (which is the same).

So you mixed up abit, the HD-manufactureres say you get 80 GB, which you do, people are just upset that they don't get 85.8 GB (80 GiBs).

Yup got it a bit mixed up. so its basically the OS' fault for saying that you have an 80GB have drive which you have, but it then also states that you have a 74.5GB hard drive, which you dont, you have a 74.5GiB hard drive. is that right?
